Question

How can the two chromosomes that make up a homologous pair differ? They can contain different alleles for the same trait. They can contain genes that code for different traits. They can contain the same genes in different orders. They cannot differ in any way when homologous.

Answer 1

They can contain different alleles for the same trait.

Answer 2

The correct answer would be "They can contain different alleles for the same trait".

Homologous chromosomes refer to the pair of chromosomes in which one is derived or inherited from the mother and other is inherited from the father.

The homologous chromosomes are similar in length, contain the same gene in the same order, and contain centromere in the same location.

The genes are same, however, they may contain different alleles.
